MEMION - Memristive Redox Transistors for Neuromorphic Computer Architectures

In order to not only keep pace with current technical developments in the field of electronic data acquisition and processing, but also to set completely new standards, alternative computer architectures are increasingly coming into focus - especially so-called neuromorphic computing. The goal here is to design architectures that reproduce the functionality of a brain as faithfully as possible and enable a high degree of plasticity. The development goal in the MEMION project is energy-efficient transistors with multi-stage switching behavior that can be used in neuromorphic computing networks.

For this purpose, Fraunhofer IPMS relies on memristive redox transistors. Compared to classical RRAM elements, where the conductivity of the channel is changed by the formation of filaments (controlled breakdown), electrochemical or redox transistors allow much higher densities of states with higher accuracy. In the project, a lithium-based synaptic transistor will be fabricated and characterized using semiconductor technologies processes.
